At the Detroit Zoo
Oliver, a male Vietnamese pot-bellied pig, is a former pet who was donated to the Zoo in 2008. He resides in the Zoo’s Barn with the miniature donkeys and other barnyard animals.
Vietnamese pot-bellied pigs have black skin with scarce hair, short erect ears, short snouts and low abdomens. They have loose skin which gives them a wrinkly appearance.
All domestic pigs have curling tails, unlike their wild relatives who typically have straight tails.
Pigs' skin is very sensitive to the sun. To stay cool and protect their skin, they wallow in the mud.
Pigs have poor vision but excellent senses of smell and hearing.
Pigs are very clean and will keep their toilet area far away from where they sleep and eat.
